I mean with things like webbrowsers it's so a group of people can have a similar experience regardless of which operating system they are on.
Each OS has its own idioms and design patterns. I don't want my experience to be more similar to what someone on Windows sees, I want it to look like the rest of the things on my computer.
Let's not pretend this is what users want. It's what developers want so they don't have to write their UI once for each platform.
Count one here. The main thing for me is: does it solve my problem? Not: is it native/does it look unique, etc.
And frankly, I think you would be pretty annoyed to try to use software that's designed to look and work like Windows 8's half-baked Metro UI if you're on Mac or Linux. What you said comes from a place of assuming it's a good baseline.

It’s what I want, as long as it integrates with native shortcuts. Great examples that I like: VScode, Obsidian. I couldn’t care less if they look native or not.
We can also argue that employment and computing in general are voluntary activities, simultaneously preserving and significantly weakening your argument.
